Objective: The species hard tick, Hyalomma anatolicum is a vector of the important pathogen
agents of both animals and human. This species is the most abundant Hyalomma tick in its
geographical zone ‎ . Hyalomma anatolicum is a vector of thileriosis and Crimean Congo
Hemorrhagic Fever (CCHF), an animal protozoan and human viral diseases respectively, in Iran
and is ‎ widely distributed throughout in this country. Some taxonomic characters on this
species was introduced ‎ but not measured. ‎ The purpose of the present
investigation was to identify valuable discriminating characters for ‎ male specimens of
Hyalomma anatolicum with the other closely related species by morphometric ‎ methods.
Material and Methods: Firstly, the collected tick specimens ‎ were identified by several
Hyalommas identification keys as Hyalomma anatolicum. Totally, nine and three quantitative
and qualitative parameters, respectively, was measured. The data measurements were analyzed
using SPSS for windows and finally the specimens were drawn by the aid of a drawing tube.
Results: The one way ANOVA test is revealed the presence of significance difference between
many quantitative parameters, except lateral groove/scutumal length ratio , also all studied
regions. The observation of the qualitative parameters shown presence and absence of these
characters in all specimens studied.
Conclusion: The amplitude and quantity of morphologic parameters of Hyalomma anatolicum
suggested that should be considered for correct identification and key preparation of this species
in further studies.
